Best way to concat strings and numbers in SQL server using Entity Framework 5?

Best way to concat strings and numbers in SQL server using Entity
Framework 5?

For some reason Microsoft decided to not support simple concat in EF5.
e.g.
Select(foo => new
{
someProp = "hello" + foo.id + "/" + foo.bar
}
This will throw if foo.id or foo.bar are numbers.
The workaround I've found is apparently this pretty peice of code:
Select(foo => new
{
someProp = "hello" +
SqlFunctions.StringConvert((double?)foo.id).Trim() +
"/" +
SqlFunctions.StringConvert((double?)foo.bar).Trim()
}
Which works fine, but is just horrid to look at.
So, is there some decent way to accomplish this with cleaner code? I'm NOT
interested in doing this client side, so no .AsEnumerable() answers
please.
